JOSEPH W. OOBURN, OF EAST WALPOLE, MASSACHUSETTS.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 228,607, dated June 8, 1880.

Application filed March 5, 1880. (Model) To all whom it may concern:

Be it known that I, JOSEPH W. GoBURN, of East Walpole, county of Norfolk, State of Massachusetts, have invented an Improvement in Door-Hangers, of which the following description, in connection with the accompanying drawings, is a specication.

This invention relates to sliding-door hangings, and has for its object such a construction thereof, as hereinafter described, as will reduce the friction to the minimum.

In this my invention I have taken an angled plate and provided one face of it wit-h a long slot to receivey within it part of the roller, and have provided theysaid plate with front and rear stops to act against axles of the antifriction roller and check its movement just before the roller arrives at the ends of the said slot. One part of this angle-plate is provided with screw-holes, by which to attach the plate to the top of the door, and the other part of the plate, or that in which the slot hereinbefore referred to is made, is made to extend horizontally backward over the top of the door, to thereby permit the roller which enters the said slot, and by which the door is rolled, to rest upon a laterally-projecting ledge or shelf connected with, say, a car or other door, the said ledge being shod with the usual angleiron. This form of hanger can be readily applied to any ordinary freight-cars having the common ledge above the door.

In some other forms of hangers the ledge in which the rollers run has been made double, and been provided with two tracks, and the rollers have been made double, with reduced bearings at their centers, about which was placed a metal strip extended upward from the top of the door between the said tracks. This class of hanger, to be applied to any ordinary freight-car, necessitates more complicated and expensive changes than by my plan.

My invention consists in a hanger composed of an angle-iron, one arm of which is provided with a long slot and roller-stops, and of a roller having journals at each end, the largest part of the said roller entering and moving longitudinally in the said slot as the door with whichthe said angle-iron is connected is moved longitudinally, the said angle-iron, when attached to the door, bearing, with the whole weight of the door, upon the end journals of the rollers used to support the door.

Figure] represents, in side elevation, one set of my hangers supposed to be attached to the top of a car-door; Fig. 2, a vertical sect-ion of the same through one of the hangers; Fig. 3, a top View of one ofthe hangers, and Fig. 4 a

rear-side elevation of one of the hangers with the roller on the track.

In the drawings, a is supposed to represent part of the side of a railroad-car or a building; b, the usual ledge, on which is the usual metal track, both commonly found in freightcars, and c the sliding door.

As so far described the parts are old, and it is for this old form of cars that I more especially designed my hangers, to thus enable their ready application without changing the car, as by adding an eXtra track.

The angle-plate, composing the ohieforlargest part of my hanger, has two arms, (as I Will call them,) d e. Arm d, or the vertical arm, when in use, has holes made in it to receive screws j', or bolts, by which to attach the hanger to the door. The arm c, or horizontal arm, has a long` slot, 2, (see Fig. 3,) which receives within it the large central part of the roller g, the said slot being substantially as wide as the roller g is broad. The end journals, 3, of this roller serve to support the parts of the arm c at each side of the slot. The roller g rests upon the usual track on the usual ledge b. The weight of the door is thrown upon the axles 3, and the rollers support the door on the track.

On the hanger are stops 4 5, that meet the journals 3 and arrest the traverse of the rollers in the slots 2, therebypreventing the large part of the roller g from striking the arm at the ends of the said slot.

Referring to Fig. 1, wherein the door is closed, if the door be slid in the direction of the arrow on it the rollers will commence to roll along the track upon the ledge d, and at the same time the rollers will gradually fall back along the said slots 2 until their journals 3 are arrested by the stop 5. During this movement of the door the friction between the roller and track and the journals and arm e is only that of I rolling friction, and Iche doo11 is by the slot of the arm 0 as the roller runs upon moved With but the minimum expenditure of the led ge and single track, all substantially as power. shown and described.
